I have seen the SES light on before, nothing too scary, but now its flashing. it goes back and forth between states, sometimes its on constantly, sometimes its flashing. has anyone had this happen before? what does that mean? nI know solid on means that its an emissions related code, but I can't remember what it means if its flashing, and I Can't find it in my owners manual right now. kinda scary, any info would be appreciated.
